Description
本发明属于汽车维修设备技术领域，涉及汽车维修举升机，特别是一种车载流动式的汽车维修举升机。
目前有两种形式的传统的汽车维修举升机：
第一种是固定式维修举升机，其立柱通常固定安装在汽车维修站地基内，使用时将需要维修的汽车移动到固定举升机的举升架上方，举升架在举升油缸的作用下，将待修汽车托举至适当高度，以方便维修人员对被修车辆的底部进行检查和修理；
第二种是移动式维修举升机，其结构如图 1
所示，其立柱固定在一个底部带滚轮的可移动底座上，使用时先将维修举升机移动至待修的车辆下方，再调整举升架托架的位置使其托住汽车的底盘，然后启动举升油缸，将待修车辆托举至适当高度以便检修。
上述两种形式的维修举升机仅适用于在固定的汽车维修站点使用，即使是第二种移动式维修举升机也只能在汽车维修站点内作小范围、短距离移动。受其局限，行驶在路途中的汽车若发生故障需进行车辆底部检修作业时，仍需租用专用拖车将故障车辆拖送至维修站，否则束手无策。以上两种传统的维修方式，不但增加维修费用，且造成时间浪费。
另外，现有的维修举升机的举升行程与作用力的行程相同，待修汽车被向上举升的作用力位移即是待修汽车的向上位移，因此待修汽车向上位移受到作用力的位移限制。
然而随着现代服务业的发展，汽车维修行业的服务意识不断提高，越来越多的客户希望能够提供上门服务，就地解决故障车辆的问题，同时也希望在检修汽车时，待修汽车的向上位移不受作用力行程的限制而上下活动行程更广。

为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
在本发明中，设装载车载流动式汽车维修举升机的汽车的前后左右等各方向作为车载流动式汽车维修举升机的前后左右等各方向。
本实施例提供的车载流动式汽车维修举升机，如图 2 所示装配在车载平台 1
上，即装配在维修人员出检所使用的汽车车箱的内部板面上，其包括水平推送机构、翻转机构、举升机构、辅助支撑机构、辅助举升机构。
如图 2 所示，水平推送机构
固定安装在所述车载平台1上，主要由水平固定导轨组件2、推送小车3和水平动力装置4构成。
如图 2 所示，
水平固定导轨组件2包括水平导轨2a和横梁，其中水平导轨2a是由两根相互平行间距为900mm、长度为2500mm的10#叉车用槽钢导轨构成，而横梁则垂直于水平导轨2a地将两根水平导轨2a焊接固定。另外，水平导轨2a沿前后方向设置，其外侧装有固定角码2b，水平固定导轨组件2通过固定角码2b与车载平台1进行螺栓固定。
如图6、7、8所示，推送小车3两侧安装有可沿水平导轨2a的导轨槽移动的小车滚轮3a，该小车滚轮3a采用承重能力较大、直径为70.1mm的叉车专用的复合滚轮轴承。
如图2所示，在本实施例中水平动力装置采用推拉油缸4，其采用缸径50mm、杆径30mm、行程1200mm的双作用油缸。由于推拉油缸4在整机工作时处于伸出状态，且承受的是拉应力，因此杆径30mm的活塞杆可以满足使用要求。推拉油缸4以其轴线平行于水平导轨2a的方向设置于水平固定导轨组件2与推送小车3之间，其中推拉油缸4的缸体端作为水平动力装置的动力输出端与推送小车3相连接，推拉油缸4的活塞杆端与水平固定导轨组件2的前端横梁端相互垂直连接。
如图2所示，水平固定导轨组件2、推送小车3和水平动力装置组成水平移动副，在本实施例中表现为水平推送机构通过固定的水平固定导轨组件2、以及推拉油缸4的伸缩实现推送小车3的水平推拉移动。
如图3、4所示，举升机构包括可立于地面的支撑组件5、可承载物体的举升组件、动力装置以及传动装置。其中举升组件和传动装置设于所述的支撑组件上，所述的举升组件与传动装置相连，所述的动力装置通过传动装置带动举升组件进行上下位移。
如图3所示，支撑组件5包括两根相互间距600mm平行且导轨槽开口相对设置的竖直导轨5a、以及用于连接两根竖直导轨5a的支撑组件横梁5f。其中竖直导轨5a是由长度2300mm的15#叉车用槽钢导轨构成。
如图3所示，动力装置是使举升组件承载汽车沿上下位移的动力源，在本实施例中动力装置采用举升油缸11。在本实施例中，举升油缸11采用缸径55mm、行程800mm的单作用油缸，举升油缸11以轴线与竖直导轨5a相平行的方向设置于竖直导轨5a与举升组件之间。
如图3、4所示，传动装置包括链轮12、链条13及链轮支架12a。链轮支架12a与动力装置的动力输出端连接，即与本实施例的举升油缸11的活塞杆端连接；链轮12活动架设在链轮支架12a上；而链条13的中部跨过链轮12，且链条13的一端与支撑组件5的支撑组件横梁5f连接，另一端与举升组件相连。
如图2、5、8、9、10所示，举升组件包括举升架10、举升滚轮10a、导板10d、以及使举升架10卡设在支撑组件5上的防坠组件。举升架10是用于承载待检修汽车的部件，举升组件即是通过举升架10的前端与链条13的一端相连。导板10d位于举升架10的前端两侧并相连接，而举升滚轮10b设置于导板10d上端以及竖直导轨5a中。导板10d与滚轮10b对应设有两套，滚轮10b在竖直导轨5a的导轨槽内沿竖直方向滚动，举升架10通过导板10d在滚轮10b的位移方向移动。在本实施例中的举升滚轮10b是直径为107.7mm、承重能力较大的叉车专用的复合滚轮轴承。
如图9、10所示，防坠组件包括有棘齿14、棘爪15、以及拉簧16。其中，棘齿14设于与举升架10相近的支撑组件上；棘爪15的形状与棘齿14相配合，且设于举升架10上；拉簧16的一端设于举升架10上，另一端设于棘爪15在远离棘齿14一侧的下端。所述的棘爪15在拉簧16的带动下，紧贴在棘齿14上并呈锁止状态。此时举升架10只能上不能下，因此即使举升油缸缸11的油管意外爆裂或链条13意外断裂，举升架10也不会因此造成坠落。
如图8、9、10所示，防坠机构还进一步包括拉管16a和操作手柄17。其中拉管16a设于所述棘爪15远离棘齿14一侧的下端，拉管16a的外侧设有供拉簧16穿设的孔，而拉簧16则勾设于所述的孔内。操作手柄17设于在举升架10上且位于棘爪15的上方，其形状与所述棘爪15上端的形状互补配合。当举升架10需要下降时，通过图10所示的箭头方向旋转操作手柄17即可打开棘爪15，使其与棘齿14脱离，呈解锁状态，再操作举升油缸11使其收回下降，举升架10才可随之下降。
如图2、13所示，辅助举升机构包括有托架10a及可调节托架高度的螺杆副10e，所述的螺杆副设于所述托架10a的底部，所述托架10a通过所述螺杆副10e设于所述举升架的端头。旋转托架10a，使其与螺杆副10e的总长度变化，即在垂直方向调整托架10a相对于举升架10的高度，如此即可实现调节托架10a的高度以及四个托架10a相互之间的距离，以适应待检修汽车的长宽不同要求。
如图2、3、4所示，当举升油缸11作为动力装置其拉长的长度为L时，与动力输出端连接的链轮支座12a升高的高度也为L，由于链条13跨过架设于链轮支座12a的链轮12上并以链轮12为滑轮，且与链条13一端铰链的是固定不动的支撑组件横梁5f，因此与链条13另一端连接的举升组件随之升高的高度为2L。因此竖直移动副是一个2：1的行程放大的链轮链条系，即动力输出端伸缩一个单位的行程，举升组件可得到两个单位的升降行程。由于举升油缸11的行程为800mm，因此举升架10的竖直举升行程最高可达1600mm。
如图2、6、7、8所示，翻转机构包括翻转动力装置和翻转耳板5b，在本实施例中翻转动力装置采用翻转油缸6。翻转耳板5b左右对称地设置在支撑组件5的两外侧中部，另外，在翻转耳板5b上还设置翻转油缸支座5c。翻转油缸6作为翻转动力装置，其一端通过小车耳板3b设于推送小车3上，另一端作为动力输出端与翻转耳板5b相连。
两支翻转油缸6采用缸径70mm、杆径30mm、行程400mm的双作用油缸，由于翻转油缸6在系统工作时处于伸出状态，且承受的是拉应力，因此杆径30mm活塞杆可以满足使用要求。
如图8所示，支撑组件5通过两翻转耳板5b的伸出端与推送小车3的两侧尾端构成具有同一回转轴线的固定铰链；推送小车3通过左右两侧中部的小车耳板3b与两翻转油缸6的缸体端构成具有同一回转轴线的固定铰链，支撑组件5通过两翻转油缸支座5c与翻转油缸6的活塞杆端构成具有同一回转轴线的活动铰链。支撑组件5与翻转油缸6的活塞杆端所构成的回转轴线的水平位置高于支撑组件5与推送小车3尾端所构成的回转轴线的水平位置。
如此，翻转耳板5b和翻转油缸6组成的翻转机构将举升机构和水平推送机构铰链。翻转机构通过翻转油缸6的伸缩实现支撑组件5的立起或放倒。当支撑组件5放倒时，整个支撑组件5可卧在推送小车3之上；当支撑组件5立起时，举升机构做竖直升降运动。
辅助支撑机构设置于支撑组件5的左右两侧近地端，呈八字形辅助支撑支撑组件以及举升机构。在支撑组件5的左右两侧均设置支撑连杆7和支撑油缸9。其中支撑连杆7的长度为700mm，两侧的支撑连杆7展开后使得两支撑点的间距可达2000mm，而支撑油缸9采用缸径63mm、杆径40mm、行程400mm的双作用油缸，可以提高整个维修举升机在工作时的稳定性。
如图2、11、12所示，在两竖直导轨5a的外侧靠地端分别设置一个支撑杆耳板5d,
在两竖直导轨5a的外侧分别设置一个支撑油缸耳板5e。支撑连杆7的一端通过支撑杆耳板5d与支撑组件5固定铰链，支撑连杆7另一端通过支座与支撑脚8固定铰链。支撑油缸9的缸体端通过支撑油缸耳板5e与支撑组件5固定铰链，支撑油缸9的活塞杆端通过设置于支撑连杆7上的支撑油缸支座7a与支撑连杆7构成活动铰链。
辅助支撑机构通过支撑油缸9的伸缩实现与支撑组件5的展开或收起。当辅助支撑机构收起时可节省整机的占用空间，展开时可加大左右两个支撑脚8的支撑距离，提高机构的稳定性，并支撑起整个维修举升机及被修车辆的全部重量。
如图6所示，当未使用汽车维修举升机时，其辅助支撑机构呈图11所示的收拢状态，举升机构呈如图6所示的卧倒状态，推拉油缸4收缩使卧倒于推拉小车3上的支撑组件5等举升机构位于车载平台1的最前端。
当需要使用汽车维修举升机构时，拖拉举升机构使推拉油缸伸长，推拉小车3后退到出检工具车的车箱后端，同时仍卧倒在推拉小车上的支撑组件等举升机构也相应地退出到车箱后端，如图7所示。
再将举升机构向下翻转，在翻转机构的作用下，支撑组件5和举升油缸11从卧倒水平状态旋转到竖直状态且其底端立于地面上，而举升架10处于水平状态，如图8所示。此时的辅助支撑机构仍呈如图11所示的收拢状态。
再将辅助支撑机构打开，使之呈如图12所示的打开状态。
将待检修汽车置于举升架10上，并通过调整辅助举升机构以适应该待检修汽车的长宽度。
最后根据需要调整举升油缸的行程，使举升架达到需要的高度，即可开始检修汽车。
